This is North Korea's first World Cup since 1966
North Korea's cunning plan to use their third goalkeeper spot for an extra striker has backfired badly.
Fifa have told them Kim Myong-Won, who usually plays as a centre-forward, will only be able to play as a goalkeeper in the World Cup.
Coach Kim-Jong Hun only named two regular goalkeepers in his squad, opting to choose Kim Myong-Won as a back-up keeper.
But in a statement, Fifa said: "The three players listed as goalkeepers can only play as goalkeepers during the Fifa World Cup and cannot play outfield. This will be communicated to the teams in the team arrival meetings and will be enforced on match days."
Carlos Vela and Alberto Medina helped Mexico to a surprise 2-1 win over World Cup holders Italy in their warm-up encounter in Brussels.
Arsenal striker Vela collected a pass from Geovani and was given space to pick his spot with a drive from 12 yards after 16 minutes.
Ten minutes from time substitute Medina beat Italy's offside trap, and from a tight right angle beat goalkeeper Guinluigi Buffon with a shot.
Italy pulled one back in the 89th when defender Leonardo Bonucci scored from close range after Salvatore Bocchetti had hit the post, but it was too little too late for the Azzurri.
Jesus Navas scored a spectacular late winner to help Spain to a 1-0 win over World Cup rivals South Korea in their warm-up match in Innsbruck.
The Seville winger fired in from 25 yards to hand the Spanish victory, after Arsenal's Cesc Fabregas had struck the crossbar from 18 yards in the first half.
South Korea's best chance fell to Chu Young Park, whose shot was blocked by Spain goalkeeper Pepe Reina a minute before the interval.
Germany came back from a goal down to win 3-1 their World Cup warm-up against Bosnia-Herzegovina in Frankfurt.
Wolfsburg striker Edin Dzeko gave Bosnia a 15th minute lead when Philipp Lahm's attempted clearance struck the Wolfsburg striker in the chest and the ball looped over goalkeeper Manuel Neuer.
Bayern Munich full-back Lahm made amends by firing in the equaliser following a mazy run in the 50th minute.
Lahm's club team-mate Bastian Schweinsteiger converted penalties in the 73rd and 77th minute to put Germany ahead in Thursday's game, the last warm-up before the three-time champion travels to South Africa.
Brazil coach Dunga has become the latest person involved with the World Cup to criticise the balls being used.
He was also unhappy that Fifa general secretary Jerome Valcke implied that Brazil were making excuses in case they performed disappointingly during the tournament.
"All he has to do is play. If he plays he will have a different opinion," said Dunga.
"The guy has never gone on the pitch, never kicked a ball, the only thing he knows how to do is talk.
"Let's put him on the field to play, to come and train here with us, with this ball, and afterwards we can talk."
Portugal's Brazilian-born striker Liedson says he will not sing the nation anthem before the Group G match between the teams out of respect for the country of his birth.
France defender William Gallas is hoping to be fit to play in France's final friendly against China on Friday.
Gallas missed training on Wednesday because of a stomach ache but coach Raymond Domenech says he should have recovered in time for the game on the island of Reunion.
Domenech originally planned to play Gallas for 90 minutes but he has had a rethink: "We have to take into account the fact he's been ill."
France have hosts South Africa, Mexico and Uruguay in their group.
Birmingham City's new striker Nikola Zigic wants to forget the memories of 2006 and prove himself at the World Cup.
The 6ft 8in Serbia forward played in Germany but failed to impress and he told Fifa's website: "I have changed a lot. I went to Germany as player with no reputation or real experience to speak of.
"Tactically, I have learned a lot and I'm in much better condition, both physically and psychologically. This is my World Cup, I think I can play a lead role and I want to show I'm a player that can do it in big games."
Lars Jacobsen believes Denmark are a dark horse who could spring a surprise in South Africa.
The Blackburn defender said: "If nobody is talking about us, we like it that way. We have not got big stars but we are a solid unit and work hard for each other.
"We had a very good qualifying campaign. We beat Sweden twice, drew one and won one against Portugal, so results speak for themselves. We did not concede many goals and that is our strength."
Japan and the Ivory Coast have arranged a specially extended friendly on Friday in order that both coaches can take a look at as many squad players as possible.
Japan coach Takeshi Okada said he would be using all 23 players at some point in the game, which will last for an extra 45 minutes.
"I want to give everyone a run-out. Both sides will give the reserve players a game," he said.
The Blue Samurai have lost four out of their last five games and are determined to break that run before the tournament kicks off in earnest.
